I'm moving towards using a still container for my kalk additions but don't want to connect with topoff due to fluctuations in topoff levels. I'd like to make hourly additions to my 225 gallon tank but I'm not sure how much hourly is safe. I plan to use a 50ml/min pump for additions through my controller. My tank uses a large amount of cal/alk, any extra needs will be made via two part additions also made hourly. Any help or tips on dosage is appreciated, thanks.
